Abstract

Currently, many people know that the use of inorganic materials in plant cultivation can have negative effects on human health and the environment. So it is very necessary to increase plant productivity by implementing organic plant cultivation technology that is sustainable and environmentally friendly. Bongohulawa Village, Tilongkabila District, Bone Bolango Regency is a village where some of the population is engaged in farming and animal husbandry, but the farming community does not utilize livestock manure and plant litter waste which is used as a basic ingredient for making solid organic fertilizer. The aim of the community service activity is to provide training in making solid organic fertilizer from cow manure and rice straw litter in Bongohulawa village, Bone Bolango subdistrict. The methods used in this activity are the material provision stage and the training stage. The training stage involves carrying out demonstrations in making solid organic fertilizer for farmer groups using cow manure, rice straw litter, EM4 bioactivator as basic ingredients. During community service activities, most farmer groups have problems with a lack of knowledge about fertilizers made from organic raw materials such as cow dung waste and rice straw waste which can improve the physical, chemical and biological properties of the soil so that the farmer group community has high enthusiasm because of the material and training regarding Making organic fertilizer and rice straw is something new for farmer groups. It is hoped that the technology provided to farmer groups can be implemented when cultivating plants, in order to produce food and a healthy and sustainable environment. In conclusion, this solid organic fertilizer activity can be applied to improve soil fertility, increase production and can open up business opportunities for organic fertilizer in attractive packaging with high selling value.

ABSTRACT

Dulupi is one of the districts in Boalemo Regency which is a center for maize production, but the high intensity of maize cultivation causes a decrease in the quality of the local land. This research aimed to determine the land suitability classes and limiting factor for maize (Zea mays L.). The research was carried out in Dulupi District of Boalemo Regency from September to Desember 2022. It employed a data matching method, matching the data for each land unit with suitability criteria. The findings revealed that the level of the land suitability for maize in Dulupi District, Boalemo Regency had theree classes of land suitability, namely moderately suitable (S2) of 88% (6314,54 Ha), marginally suitable (S3) of 10% (763,89 Ha), and not suitable (N) of 2% (41,15 Ha). In contrast, the yield-limiting factors were nutrient retention, avaible nutriens (N, P, K), erosion hazard, drainage, and effetive depth. With the improvment efforts, the yield limiting factors in the potential land and suitability increased to S2 and S3 classes.

Abstract

Black soils store a high amount of soil organic carbon (SOC) and play a crucial role in climate change, food security, and land degradation neutrality. However, data and information regarding black soils in tropical regions, including Indonesia, are limited. This study aimed to characterize and identify the utilization of black soils in Indonesia based on legacy soil survey data. We collated 142 soil pedon samples of Mollisols from articles, technical reports, and existing datasets. The site information (site position, elevation, land use type, parent material) and selected physicochemical properties were stored in a spreadsheet, from which exploratory data analysis was conducted. The result showed that the median SOC content was 1.53%, ranging from 0.6 to 8.2 %; cation exchange capacity was 30 cmol kg-1, ranging from 9 to 95 cmol kg-1; base saturation was 87%, ranging from 11 to 100 %; and bulk density was 1.21 g cm-3, ranging from 1.13 to 1.36 g cm-3. Other soil characteristics (particle size distribution, exchangeable bases, pH, pore, and water retention) varied with horizon type and land use/land cover. The black soils have been used for paddy fields, dryland farming, and gardens with low management intensity. Main cultivated crops include rice (Oryza sativa), corn (Zea mays), cassava (Manihot esculenta), sweet potato (Ipomoea batatas), and nutmeg (Myristica fragrans), clove (Syzygium aromaticum), coconut (Cocos nucifera), and cocoa (Theobroma cocoa). Threats to black soil functions include soil erosion, carbon loss, and nutrient imbalance. Soil and water conservation measures, integrated soil nutrient management, and agroforestry are among the best land management practices for black soils.

Abstract

Maize has attracted the attention of local governments due to its high yield potential and economic prospects, but the strategic value of this commodity has not been specific to particular locations. Therefore, this study aimed to assess degraded land suitability and determine the regional comparative advantages for maize development in the Gorontalo sustainable agriculture areas. The suitability class was assessed using Automatic Land Evaluation System software, while comparative advantages were determined using input-output and regional analysis. The input-output analysis was based on maize farming data from interviews with 80 farmers. This study also employed location quotient, specialization index, and localization index analyses based on maize, rice, and soybean production data for 2014, 2016, and 2018. The results showed that land degradation caused by soil erosion was dominated by moderate, heavy, and very heavy categories. Most of the actual land suitability for maize was classified as marginal suitable (S3) but became very suitable (S1) and moderately suitable (S2) after the limiting factors were improved. Furthermore, maize was profitable for the land suitability classes of S1, S2, and S3, and the commodity was most concentrated in Mootilango District. Based on the results, land management recommendations followed a pattern of recommendation I > II > III > not recommended.

AbstractThe lack of water availability and the short period of maize growth has the potential to be the main obstacles to achieving optimal production. Therefore, this research aimed to determine the water availability and long growth period (LGP) of maize plants in Boalemo Regency, which was included in the agrokilmat zone E2. Rainfall and temperature data from Saritani, Tangkobu, and Bubaa climate stations in Boalemo Regency were used over ten years, from 2012 to 2022. The soil profile moisture content data used pF 2.5 and pF 4.2 while the tool used Cropwat8.0. Furthermore, the determination of available water and LGP was conducted using a water balance table with the Thornwaite method. The results showed that the highest and lowest water availabilities were 556 mm and 118 mm at the Saritani and Tangkobu climate stations, with a maximum LGP of maize at 242 days and 181 days, respectively. Based on climate stations, the availability of water and the amount of LGP follow the pattern of Saritani climate station > Bubaa climate station > Tangkobu climate station.
